For the second consecutive year, the "High Energy Physics" team of physicists, computer scientists, and network engineers have won the Supercomputing Bandwidth Challenge with a sustained data transfer of 101 gigabits per second (Gbps) between Pittsburgh and Los Angeles. This is more than four times faster than last year's record of 23.2 gigabits per second, which was set by the same team.
The Hale Telescope on Palomar Mountain has been gathering light from the depths of the universe for 55 years. It finally sent some back early last week as a team of astronomers from the California Institute of Technology, the Jet Propulsion Laboratory and the University of Chicago created an artificial star by propagating a 4-watt laser beam out from the Hale Telescope and up into the night sky.
Nicotine is responsible for more than four million smoking-related deaths each year. Yet people still smoke. Why? One reason is the stranglehold of addiction, started when nicotine enhances the release of a neurotransmitter called dopamine, a chemical messenger that induces a feeling of pleasure. That's what smoking, presumably, is all about.
When it comes to mitigating the harmful impacts of environmental pollution--size does matter . . . or, at least, that's the hypothesis that California Institute of Technology professors Janet Hering and Richard Flagan will be testing.
The California Institute of Technology has launched a university-wide initiative called Information Science and Technology (IST)--drawing back the curtain on the nature of information itself and redefining the way we approach, understand, and use science and engineering. IST will cut across disciplines, eventually involving over 25 percent of all faculty and nearly 35 percent of students on campus, likely altering the Institute's intellectual and organizational landscape.
Thanks to a $13,254,000 grant from the Gordon and Betty Moore Foundation, Caltech has established the Tectonic Observatory, under the direction of Avouac, with the ultimate goal, he says, of "providing a new view of how and why the earth's crust is deforming over timescales ranging from a few tens of seconds, the typical duration of an earthquake, to several tens of million of years."
Writing in the current issue of the journal Science, Institute for Systems Biology immunologist and technologist Leroy Hood and California Institute of Technology chemist Jim Heath and their colleagues explain how a new approach to the way that biological information is gathered and processed could soon lead to breakthroughs in the prevention and early treatment of a number of diseases.
Sossina Haile, an associate professor of materials science and chemical engineering at the California Institute of Technology, is an expert in fuel cells, and she has been whittling away at the heat problem for years. Now she and her colleagues have not only solved the problem, they've smashed it. They've brought the temperature down to about 600 degrees Celsius (1100 degrees Fahrenheit), while achieving more power output than others are achieving at the higher temperatures--about 1 watt per square centimeter of fuel cell area.
Cosmologists from the California Institute of Technology have used observations probing back to the remote epoch of the universe when atoms were first forming to detect movements among the seeds that gave rise to clusters of galaxies. The new results show the motion of primordial matter on its way to forming galaxy clusters and superclusters. The observations were obtained with an instrument high in the Chilean Andes known as the Cosmic Background Imager (CBI), and they provide new confidence in the accuracy of the standard model of the early universe in which rapid inflation occurred a brief instant after the Big Bang.
